Start off a song for me please?

I am writing a song about this guy I like. Not one of those terrible "oh woe is me, I wish he loved me" type songs it's just about how I think about him all the time and I see him as this perfect guy. It's about all the reasons I like him and what he des, it's going to be called "Nick;s Song". Only problem is I am having major problems with starting it off. I can't get the first few lines out! If you have any lyric suggestions then go ahead! All I need is a beginning but it's not coming to me.
